Description

[Detailed description of the invention] This invention relates to a top light that can be easily attached to a storage frame provided with a translucent plate over an opening in a roof, etc., even in high places with poor footing, and is watertight. The purpose of the present invention is to provide a top light that also has excellent airtightness.

That is, in the top light according to the present invention, the storage frame A is tilted and fixed to the opening of the house that opens almost upward, and the upper transparent plate 3 and the lower transparent plate 2 are assembled into square frames. It constitutes an independent frame-assembled light-transmitting plate, and has mounting edges 24 and 28 protruding from the four circumferences of the upper frame-assembled light-transmissive plate 3, and is attached to the upper and lower parts within the storage frame A through airtight members 15 and 32. The frame-assembled transparent plates 3 and 2 are housed, and one mounting edge 24 of the upper frame-assembled transparent plate 3 is hooked to the upper frame a1 of the inclined upper part of the storage frame A, and the other three mounting edges are 24 and 28 are screwed to the lower frame a2 and both vertical frames a3 of the storage frame body A.

Embodiments of the present invention will be described below with reference to the drawings.

Generally, top lights are often installed in openings made in the roof.

However, recently, mainly due to the expansion of indoor space,
As shown in FIG. 1, a bay window 40 in which the window protrudes from the outer wall and a bay window 41 structure in which a part of the outer wall is protruded have been proposed and implemented.
Since a solar light receiving surface is also formed in t41a, a top light can be attached to these parts by providing an opening almost upward, and is not limited to being attached to a roof.

First, in FIGS. 2 and 3, the symbol W indicates an opening.

This opening W is formed in a rectangular shape in a part of the roof R, and is usually limited by a peripheral frame 1 that projects upward from the roof R surface.

The opening surface at the upper end of this peripheral frame 1 is inclined along the roof slope.

Note that R□ represents a roof plate, and R2 represents a draining plate that slopes from the center of the rear portion of the peripheral frame 1 in the shape of a gable roof.

A storage frame A is mounted on the peripheral frame 1 of the aperture part, and a lower transparent plate 2 and an upper transparent plate 3 which are stacked vertically are disposed inside this storage frame A to constitute a top light. do.

The transparent plate storage frame A has an upper frame a1 at an inclined upper part, a lower frame a2 at an inclined lower part, and a vertical frame a3 formed into a rectangular frame corresponding to the shape of the opening W.

These upper and lower and vertical frames a1, a2, and a3 respectively have bottom sides 4, 5, and 6 forming the frame bottom, and wall sides 7, 8, and 9 rising from the outer ends of these bottom sides and forming the frame walls.
Equipped with.

Further, the bottom sides 4° 5 and 6 are provided with screw holes 4a, 5a and 6a for attaching the frame to the opening peripheral frame 1 and the holding edges 4b, 5b and 6b of the lower transparent plate 2, and the wall sides 4. 7
．． 8 and 9 are provided with mounting portions for the upper transparent plate 3.

This mounting portion will be described later. Note that since the top light is installed at a high place, each of its constituent members is required to be lightweight, but on the other hand, since the top light is placed in a position where it is strongly affected by wind, the frame body is required to be strong.

Therefore, it is necessary to construct it from a light metal such as aluminum and to increase the strength of the structure.

For this reason, it is preferable to form a hollow reinforcing portion as shown in FIG. 3 in a part of the wall side 9 of the vertical frame a3, which is shorter than the upper and lower frames al and a2, to increase the structural strength.

In addition, by forming a hollow part in a part of the wall side 9 and extending its outer end vertically, when a top light of the same type as this example is installed in a bay window, etc., it is possible to make the hollow part extend vertically. The protruding parts 9b and 9d can be used as attachment edges of the bay window side wall 13, and the frame can be used in many ways.

The upwardly extending portion 9b also has the effect of south-back binding.

Each of the frame members al, a2 and a3 is framed in a rectangular shape,
The bottom sides 4, 5 and 6 are placed on the opening peripheral frame 1 via the leg lines 4C95c and 6c and fixed with screws.

In this case, the lower ends of wall sides 7°8 and 9 are connected to bottom side 4.
, 5 and 6, the skirt portion 9e is configured to hang further down than the joints with the storage frame A and the peripheral frame 1, which not only has the effect of hiding the attachment portion between the storage frame A and the peripheral frame 1, but also facilitates the positioning of the frame. Further, by forming an airtight piece fitting groove 9C inside the lower end and fitting the airtight piece 11 therein, it is possible to prevent outside air from entering into the storage frame A, and also has the effect of returning rain.

In addition, especially when the protruding edge 12 is made to protrude downward from a predetermined position on the bottom side 4 of the upper frame a1, the protruding edge 12 is hooked to the outer edge of the peripheral frame 1, so positioning during installation is facilitated. It can also support part of the toplight load.

Next, the lower transparent plate 2, which is assembled into a rectangular frame, is placed inside the frame.

The light-transmitting plate is not limited to a glass plate, and may be a synthetic resin plate or the like as long as it has light-transmitting properties.

In this case, if it is placed directly on the bottom side of the storage frame A, the condensation water generated on the lower surface of the transparent plate 2 has no opening to drain, so the lower frame A
2, flows down the inside of the peripheral frame 1 and indoors.

To prevent this, each bottom side 4.5.6 of the storage frame A
It is preferable to raise the light transmitting plate holding edges 4bt5b, 6b from the lower frame A2 and to cut out water guides i16, 16 in the bottom side 5 of the lower frame A2 and the base of the holding edge 5b, respectively.

Since the condensed water generated on the transparent plate 2 flows outdoors along the water guide grooves 16 and 16', there is no risk of it flowing indoors.

While the airtight member 15 is hooked to the hook-shaped protruding edge 14 provided at the tips of the holding edges 4b, 5b, and 6b, the four circumferences of the transparent plate 2 are assembled into a frame, and the transparent plate 2 is attached to the airtight member 15 of the holding edge. Place it on top.

At this time, the transparent plate support member 10 is placed inside the lower frame a2.

Note that if a bent handhold edge 19 is formed protrudingly on the upper part of the vertical stile 17 and/or horizontal stile 18, 18' of the light-transmitting plate 2, the lower light-transmissive plate 2 can be attached with the hand on this handhold edge 19. Since it can be handled with ease, the work of attaching it to the storage frame A becomes easier.

Next, the upper transparent plate 3 is disposed on the lower transparent plate 2.

In this case, the upper transparent plate 3 is the lower transparent plate 2 and the storage frame A.
It is necessary to maintain watertightness and airtightness, and it is also required to have an excellent drainage effect.In addition, since the installation work of the transparent plate 3 must be carried out on a narrow roof with poor footing, it is necessary to have a structure that is easy to handle. There must be.

Therefore, in the present invention, the translucent plates are assembled into frames, one of the frames is hung on the slanted upper part of the frame, and the other frame is fixed to the storage frame either directly or through the presser edge. .

That is, as shown in FIGS. 2 and 3, a pair of vertical and horizontal frames 2 each having a translucent plate fitting groove 36 formed inside a rectangular cylindrical body.
0 and 21 are assembled into square frames, and the above-mentioned fitting groove 3 is
The light-transmitting plate 3 is fitted into the holding member 6 through the holding member 22.

It should be noted that it is difficult to completely maintain watertightness and airtightness between the two members by simply interposing the holding member 22 between the transparent plate 3 and each frame, so at least the upper surface part 3a of the transparent plate and the protrusion of the frame are It is preferable to attach a sealing material 23 between it and 95 for sealing.

A mounting edge 24 is integrally formed on the outside of the horizontal stile 21, and an upper horizontal stile 21 corresponding to the upper frame a1 of the storage frame A is formed.
The tip of the mounting edge 24 of ' is bent downward into a hook shape to form a latching groove 25.

Further, a mounting edge 28 is integrally formed to project outward from the vertical stile 20.

Furthermore, the upper transparent plate attachment portions of the upper and lower and vertical frames a1, a2, and a3 shown above are constructed in the usual manner.

That is, on the outside of the upper end of the upper frame a1 is the upper horizontal stile 2.
A locking edge 26 corresponding to the locking groove 25 of 1' is provided protrudingly, and a screw catch groove 27 is formed on the outside of the upper end of the lower frame a2, and a screw catch is also formed on the inside upper end of the vertical frame a3. A groove 29 is formed.

When attaching the upper stile-assembled translucent plate 3 to the storage frame A, first insert the upper frame a1 of the frame A into the locking groove 25 formed at the end of the upper horizontal stile 21' of the translucent plate 3. The latching edge 26 protruding outward from the upper end is latched, and then the mounting edge 28 and the mounting edge 24 are attached to the other three vertical and horizontal frames 20 and 21 of the transparent plate, respectively, to the corresponding vertical frame a3 and lower frame. It is suspended over the upper end of a2, and the screw receiver is screwed into the grooves 29 and 27 from above the mounting edges 28 and 24.

Furthermore, an airtight member 32 is fitted into the fitting groove 31 formed at the bottom of the frames 20, 21 of the transparent plate 3, and the airtight member 32 is brought into contact with the frame surface of the lower transparent plate 3 during installation. top and bottom 2
, 3 to maintain airtightness.

The airtight member 32 may alternatively be mounted on the lower stile 17, 18.

In this way, the mounting edge 2 of one side stile 21 of the upper transparent plate 3
4 is hooked to the upper end of the upper frame a1 from the outside of the upper part.

In other words, the installation work for this portion is completed by simply engaging the locking groove 25 formed at the end of the mounting edge 21 with the locking edge 26 of the upper frame a1.

Therefore, not only is there no need for detailed positioning of the upper and lower frames al, a2 and the horizontal stile 21, but there is also no need for screwing, so handling is easy and there is no fear of rain and ice entering through the screw holes.

Furthermore, since the transparent plate 3 can be easily removed, repair work is also facilitated.

Also, for the other three frames 20 and 21, the mounting edges 28 and 24 are suspended from the frame A and fixed with screws.
It drains well, has excellent watertightness and airtightness, and is able to withstand strong winds.

As mentioned above, the upper and lower transparent plates 3 and 2 are configured as independent frame-assembled transparent plates, so when the double transparent plates are assembled in advance and housed in the storage frame, Compared to this, the weight is small, so when installing it in a place where it is difficult to install because of poor footing, such as the roof of a house, it can be installed separately when it is stored in the storage frame A, making the work very easy.

Moreover, since the upper and lower transparent plates 3.2 are housed in the storage frame via the airtight member 15.32, the upper frame-assembled transparent plates 3.2
The upper and lower frame-assembled transparent plates 3 and 2 can be fixed without wobbling by a simple operation of fixing them in the storage frame A, and also have good watertightness and airtightness.

Next, for example, if two or more transparent plates must be installed in series because the opening is long, adjacent transparent plates should be connected via mullions as shown in Figure 3. .

That is, the cross section of the mullion 33 consisting of the base side 33a and the hollow standing side 33b rising from the center of the base piece 33a is configured as an inverted T-shape, and there is a transparent plate holding edge above the base side 33a. 33c protrudes, and the upper and lower transparent plates 3.2 are placed on top of each other on this holding edge 33c, and the mounting edge 35 of the frame 34 of the upper transparent plate 3 suspended on the mullion 33 is attached to the holding edge 33c. Fix it by screwing it into place.

Of course, in this case as well, it may be fixed via the presser edge.

Note that the mullion 33 may be fixed with screws between the upper and lower frames al and a2.

Furthermore, when screwing a screw into the groove 29 of a screw holder with a U-shaped cross section, the grooved screw holder only has countersunk on both sides, and the entire circumferential surface of the screw is not in contact with the groove. .

For this reason, the screw receiver has a rather weak binding force between the groove 29 and the screw, and there is a risk that the screw may come out of the groove due to being blown by the wind during strong winds.

Therefore, the cross-sectional shape of the groove in the screw receiver is preferably
As shown in the figure, it is shaped like a cross, with a wide opening in the middle of the groove.

Such a cross groove 29' can not only be used as a screw groove, but also allows the head 37a of the bolt 37 to engage with the wide mouth part 29'a, and also allows the cap nut 38 to be inserted from the outside.
The transparent plate 3 and frame member a3 can be tightened with
The bonding strength between the two will be greatly improved.

The same applies to the grooves of the screw receivers of the lower frame a2, the mullion 33, etc.

As explained in detail above, according to the top light according to the present invention, the upper and lower transparent plates 3 and 2 are configured as independent frame-assembled transparent plates, so that double transparent plates are used. Compared to the case where the boards are assembled in advance and housed in the storage frame,
Since the weight is small, especially when installing in a place where scaffolding is poor and construction is difficult, such as on the roof of a house, it can be constructed separately when it is stored in the storage frame A, making the work very easy.

Similarly, by simply hooking the end of one of the mounting edges 24 of the upper frame-assembled transparent plate 3 to the upper end of the upper frame of the inclined upper part of the storage frame A from the outside of the upper part, the installation work for this part is completed. Complete.

Therefore, the upper and lower frames al. As for the Al and the horizontal stile 21, there is no need for detailed positioning at all, and there is no need for screwing, so handling is easy and there is no fear of rainwater entering through the screw holes.

Moreover, since the upper and lower transparent plates 3 and 2 are housed in the storage frame via the airtight member 15.32, the upper frame-assembled transparent plate 3
The upper and lower frame-assembled transparent plates 3 and 2 can be fixed without wobbling by a simple operation of fixing them in the storage frame A, and also have good watertightness and airtightness.

Therefore, the practical effect is very large.
